Abstract (en)
A capability enabling method and apparatus are provided, to resolve a prior-art problem that security of executing a service by using a TEE + SE security architecture cannot be ensured. In this application, an SE establishes, with a TEE, a session used for communication. The SE sends, to the TEE by using the session, an obtaining instruction used to obtain a security certificate of the TEE. The TEE receives, by using the session, the obtaining instruction from the SE. After receiving the obtaining instruction, the TEE generates the security certificate based on attribute information of the TEE, and sends the generated security certificate to the SE by using the session. After the SE receives, by using the session, the security certificate sent by the TEE, the SE determines, based on the security certificate and a preset security policy, that the TEE is in a secure state. After the SE determines that the TEE is in the secure state, the SE enables a first capability for a third-party service in the SE, where the first capability is implemented based on a second capability of the TEE.
